Haven't seen this link posted before (I could be wrong) but this url lists all of the rest type defimnitions with detailed instructions for each one. There's a section for each type including:

* Soft Reset
* System (Warm) Reset
* Hard Reset
* In-Cradle (rechargeable devices only)
* Power Down (AAA battery devices only)
* Battery Disconnect (Treo 600 only)
* Zero Out (Tungsten T5; Treo 650 only)
* Quick Erase, Secure Erase (LifeDrive only)
* Recovering your data after a hard reset


Since this was edited May 26, 2006 (post 700w/700p) I kinda curious as to the "650 only" thing on the zero out reset.
